    摘要:

    目的 探讨8周的太极拳结合振动复合式训练对α运动神经元终池及γ反射弧兴奋性的影响。方法 55位健康大学生分为4组:太极振动组(TAV)、太极拳组(TAI)、振动组(VB)以及无太极或振动介入的对照组(CON),进行为期8周、每周3次训练;训练前后以电刺激诱发比目鱼肌H-reflex与M-wave信号,并以反射槌敲击Achilles tendon测量T reflex信号。结果 经8周单纯振动训练后,Hmax/Mmax与T reflex/Mmax出现显著下降(P<0.05),8周太极振动组T-reflex/Mmax显著提高(P<0.05),且其变化率显著大于振动组(P<0.05)。结论 虽然单纯振动刺激可降低安静时α运动神经元终池兴奋性,但太极振动复合式训练对肌梭刺激较大,从而提高γ反射弧兴奋性;太极拳结合振动的复合式训练能对下肢外围神经产生适应性,显示结合太极拳与振动刺激两种训练具有可行性。

    Abstract:

    Objective To investigate the effects of Tai Chi Chuan combined with vibration training on the excitability of α-motorneuron pool and γ-reflex arc. Methods 55 healthy college students were divided into Tai Chi Chuan + vibration training (TAV) group, Tai Chi Chuan training (TAI) group, vibration training (VB) group, and control group (CON) for 8 weeks with 3 times training per week. Each time at pre-and post-training, H-reflex and M-wave were recorded by electrical stimulus induced on soleus muscle. T-reflex was also collected by knocking on the Achill tendon. Results After 8-week training, the ratios of Hmax/Mmax and T-reflex/Mmax in VB group were significantly decreased (P<0.05), while the ratio of T-reflex/Mmax in TAV group was significantly increased (P<0.05), and the change percentage of T-reflex/Mmax was significantly higher than that in VB group (P<0.05). Conclusions Although the vibration training could decrease the resting excitability of α-motorneuron pool, the Tai Chi Chuan combined with vibration training could give the muscle spindle stronger excitement so as to further induce the high excitability of γ-reflex arc. It indicated that the Tai Chi Chuan combined with vibration training is feasible since the neural adaptation around peripheral neuron system could be induced after such kind of training.
